The Signal Processing group (http://www.sigproc.uni-oldenburg.de/) at
the Department of Medical Physics and Acoustics, University of
Oldenburg, Germany is seeking to fill the position of a PhD student in
the PhD Program "Signals and Cognition". This full-time position is
available for initially 3 years, with a monthly stipend amounting to
min. 1500 € (net).
The title of the envisaged research project is "Multi-microphone speech
enhancement using brain computer interfaces" (SigCog 05). In many speech
communication applications, such as hearing aids and teleconferencing
systems, the recorded signals consist of a mixture of different speakers
and background noise. Although in the last decades several
multi-microphone speech enhancement techniques (e.g. fixed and adaptive
beamforming, Multi-Channel Wiener Filter, blind source separation) have
been developed, they all rely on pre-defined assumptions about the
target speaker. E.g. in hearing aids the target speaker is typically
assumed to be in front of the user, whereas in teleconferencing systems
it is assumed to be the loudest speaker. In this PhD project we will
investigate brain computer interfaces to control multi-microphone speech
enhancement techniques, in order to enhance the target speaker to which
the user is attending. This PhD project will consist of developing
methods for decoding the neural signals to find out to which speaker the
user is attending and integrating them with multi-microphone speech
enhancement algorithms.
The Department of Medical Physics and Acoustics offers an attractive
scientific environment in an international team of scientists and access
to state-of-the-art acoustical equipment and labs. We are seeking for
candidates with a Master (or equivalent) degree in electrical
engineering, biomedical engineering, computer science or physics, who
have excellent grades and a solid scientific background in signal
processing, acoustics and/or pattern recognition. Familiarity with
scientific tools and programming languages such as MATLAB or C, as well
as excellent English language skills are required. Research experience
in any of the mentioned fields and a strong interest in
interdisciplinary and application-oriented work is desirable.
Please send your application including a letter of motivation, CV and a
copy of the university diplomas and grades until 01.11.2013 to Carl von
Ossietzky Universität Oldenburg, Department of Medical Physics and
Acoustics, Signal Processing Group, Prof. Dr. Simon Doclo, 26111
Oldenburg, Germany, or electronically to simon.doclo@xxxxxxxxxxxxxxxx
The Carl von Ossietzky Universität Oldenburg strives to increase the
proportion of women in science, so we especially encourage female
candidates to apply. Handicapped applicants will be given preference if
equally qualified.
